As we noted earlier, all pre-order "exclusive" DLC for Batman: Arkham City will be made available for purchase after release. GameStop has inadvertently confirmed this, revealing the dates and prices for three upcoming DLC packs.

The latest episode of Qore, available free for PlayStation Plus subscribers, showcases two enemies for the upcoming Batman simulator. The Mad Hatter makes his first appearance for the franchise, while Poison Ivy makes a welcome return.

Batman: Arkham City has "gone gold," according to developer Rocksteady. That means development has finally completed and the game is now being printed and packaged, to be shipped for its big October 18th release.
